Chapter 1 SPMU296 – April 2013 Board Overview The Tiva™ C Series TM4C123G LaunchPad Evaluation Board (EK-TM4C123GXL) is a low-cost evaluation platform for ARM® Cortex™-M4F-based microcontrollers. The Tiva C Series LaunchPad design highlights the TM4C123GH6PMI microcontroller USB 2.0 device interface, hibernation module, and motion control pulse-width modulator (MC PWM) module. The Tiva C Series LaunchPad also features programmable user buttons and an RGB LED for custom applications.
Kit Contents www.ti.com 1.1 Kit Contents The Tiva C Series TM4C123G LaunchPad Evaluation Kit contains the following items: • Tiva C Series LaunchPad Evaluation Board (EK-TM4C123GXL) • On-board In-Circuit Debug Interface (ICDI) • USB micro-B plug to USB-A plug cable • README First document 1.2 Using the Tiva C Series LaunchPad The recommended steps for using the Tiva C Series TM4C123G LaunchPad Evaluation Kit are: 1. Follow the README First document included in the kit.
BoosterPacks 1.4 www.ti.com BoosterPacks The Tiva C Series LaunchPad provides an easy and inexpensive way to develop applications with the TM4C123GH6PM microcontroller. Tiva C Series BoosterPacks and MSP430 BoosterPacks expand the available peripherals and potential applications of the Tiva C Series LaunchPad. BoosterPacks can be used with the Tiva C Series LaunchPad or you can simply use the on-board TM4C123GH6PM microcontroller as its processor. See Chapter 2 for more information.
Chapter 2 SPMU296 – April 2013 Hardware Description The Tiva C Series LaunchPad includes a TM4C123GH6PM microcontroller and an integrated ICDI as well as a range of useful peripheral features (as the block diagram in Figure 2-1 shows). This chapter describes how these peripherals operate and interface to the microcontroller. Figure 2-1.
Functional Description www.ti.com Most of the microcontroller signals are routed to 0.1-in (2.54-mm) pitch headers. An internal multiplexer allows different peripheral functions to be assigned to each of these GPIO pads. When adding external circuitry, consider the additional load on the evaluation board power rails. The TM4C123GH6PM microcontroller is factory-programmed with a quickstart demo program.
Functional Description www.ti.com 2.1.4 User Switches and RGB User LED The Tiva C Series LaunchPad comes with an RGB LED. This LED is used in the preloaded RGB quickstart application and can be configured for use in custom applications. Two user buttons are included on the board. The user buttons are both used in the preloaded quickstart application to adjust the light spectrum of the RGB LED as well as go into and out of hibernation.

In-Circuit Debug Interface (ICDI) www.ti.com There is no external battery source on the Tiva C Series LaunchPad Hibernation module, which means the VDD3ON power control mechanism should be used. This mechanism uses internal switches to remove power from the Cortex-M4 processor as well as to most analog and digital functions while retaining I/O pin power. To measure the Hibernation mode current or the Run mode current, the VDD jumper that connects the 3.3 V pin and the MCU_PWR pin must be removed.
Chapter 3 SPMU296 – April 2013 Software Development This chapter provides general information on software development as well as instructions for Flash memory programming. 3.1 Software Description The TivaWare software provided with the Tiva C Series LaunchPad provides access to all of the peripheral devices supplied in the design. The Tiva C Series Peripheral Driver Library is used to operate the on-chip peripherals as part of TivaWare.
Programming the Tiva C Series LaunchPad Evaluation Board 3.4 www.ti.com Programming the Tiva C Series LaunchPad Evaluation Board The Tiva C Series LaunchPad software package includes pre-built binaries for each of the example applications. If you have installed TivaWare to the default installation path of C:\ti\TivaWare_C_Series_, you can find the example applications in C:\ti\TivaWare_C_Series_\examples\boards\ek-tm4c123gxl .
